5x-3 = 11+12x

You correctly recognized that you need to isolate the x terms on one side. However, if you subtract 12x from the right, you need to subtract 12x from the left, not add. So:

-7x - 3 = 11

You didn't make any other mistakes after that point. Following the same steps from here should give you the right answer,
